A new study finds that Louisiana's second Gulf of Mexico dead zone stretches at least from the Chandeleur Sound off Louisiana to Alabama's Dauphin Island — and could be bigger.
The Lake Pontchartrain Basin Foundation says it could check only as far as Dauphin Island last year. Officials hope to get other states to extend the reach of studies that will start later in February.
In 2010, scientists found a 250-square-mile area where oxygen levels were too low to support life in the Chandeleur Sound.
The one found last year was more than 1,000 square miles. Foundation head John Lopez said Wednesday the area probably didn't grow — the scientists just looked farther.
